Water Heater Installation & Replacement in Carrollton, TX
Whether it's a like-for-like swap or a full upgrade, a new water heater in Carrollton gets sized, installed to current code, and permitted correctly the first time.
Call (469) 856-7724Installing a new water heater is a different job from repairing an old one, even when it's the same size tank going into the same spot. A new installation means sizing the unit correctly for the household, meeting current code on venting, the temperature and pressure relief valve, and expansion tank requirements, and pulling the permit Carrollton's building department requires for this work.
We handle the whole process: removing and disposing of the old unit, installing and connecting the new one, and being present for the city inspection that closes out the permit.
Sizing a Water Heater Correctly
A water heater that's too small runs out of hot water during normal household use. One that's too large wastes energy keeping more water hot than the household actually needs. Sizing comes down to household size, peak usage times, and how many bathrooms and appliances draw hot water at once.
| Household Size | Typical Tank Size (Gallons) |
|---|---|
| 1 to 2 people | 30 to 40 |
| 3 to 4 people | 40 to 50 |
| 5 or more people | 50 to 80, or a tankless system |
What Carrollton's Permit Process Involves
Water heater installation in Carrollton generally requires a plumbing permit. The completed work has to meet current code even if the old setup predates it. That means a properly rated temperature and pressure relief valve, correct discharge piping, a drain pan where the installation location requires one, and an expansion tank if the home runs a closed plumbing system. An inspector reviews the finished installation before the permit closes out.
We pull the permit as part of the installation and schedule around the inspection, so there's no separate step for the homeowner to manage.
New Installation Versus Replacing an Existing Unit
A brand-new installation, in a home that never had a water heater in that location, involves more work than replacing an existing unit: running new supply lines, venting, and often a dedicated electrical circuit or gas line. Replacing an existing unit in the same location is usually faster, though it's still worth checking whether the existing venting and connections meet current code rather than assuming they do.
For a straightforward swap where the old unit failed and needs to be diagnosed first, our water heater repair page covers that side of the decision. For anyone specifically considering a tankless system instead of another tank, our tankless water heater page covers what that conversion involves in a hard water city like Carrollton.
Choosing Between Gas and Electric
A replacement is a natural point to reconsider fuel type, not just tank size. Gas units generally recover faster after heavy use and cost less to run month to month where natural gas is available, but they need proper venting and combustion air. Electric units are simpler to install where gas isn't already run to the location, with no venting requirement, though they typically take longer to recover a full tank of hot water after heavy demand.
Switching fuel types during a replacement, rather than defaulting to whatever was there before, is worth discussing upfront since it changes the scope of the permit and the work involved.
